I introduced my mother to stocks recently, she then proceeds to hold SQQQ for the past four months, losing $500k and counting

It started off nice and good with some google, amazon, voo, twitter (questionable). Then I assume she watched some YouTube videos and got into confirmation bias mode and pretty much every other bias. She’s in her 50s by the way.

Still holding to this day, still trying to talk some sense into her to this day… I have tried to no avail to explain decay and biases. What the hell can I do?
